Abstract

PCT No. PCT/FI94/00278 Sec. 371 Date Mar. 11, 1996 Sec. 102(e) Date Mar. 11, 1996 PCT Filed Jun. 21, 1994 PCT Pub. No. WO95/01079 PCT Pub. Date Jan. 5, 1995A folded dielectric film element is provided which converts energy. The film element includes at least one dielectric film that is bent into folds and provided with electrodes. The electrodes are arranged in the folds so that different electrodes are placed in successive folds. The strength of an electric field increases in one fold and decreases in a successive fold.
